This study investigated mobilization and leaching of colloidal matter and dissolved organic carbon from two aggregated soils (Andisols) and a single grain soil (sand) during rainfall irrigation using column experiments. Results show that the cumulative colloid leaching from both aggregated and single-grained soils increased linearly with the square root of time at low EC effluents. This suggests that the colloid leaching is controlled by diffusion-limited kinetics. The mechanism of colloid detachment was also examined based on the relationship between the colloid concentration and the reciprocal of the square root of EC., text, application/pdf}, pages = {104--109}, title = {降雨による土壌コロイドと溶存有機物の流出特性<速報>}, volume = {38}, year = {2005}, yomi = {カワモト, ケン and コマツ, トシコ} }
